The 3d transition metal ion complexes of some 4,5-diphenylimidazole azo derivatives have been isolated and characterized by chemical analysis, conductance, electronic and IR spectra.These dyes are characterized by a high tendency towards complex formation with the neutral molecules coordinated to the metal ion as bidentate ligands.The molecular formula of the 1:1 and 1:2 complexes are suggested to be and or *2H2O respectively, where X=Cl- or NO3-.The different bands observed in the visible spectra of methanolic solutions of the complexes have been assigned to the possible electronic transition type (L-->MCT and d-d).It is suggested that the complexes studied have a distorted octahedral geometry. - Keywords: Coordination compounds; Azoimidazole; Transition metals
